If you have inactive govs as a king and you meet the criteria for the relocation process then the game itself will send you a message asking you if you would like to relocate to a new area with more active governors.Same goes for governors. They will get an option to relocate to a more active kingdom. This is controlled by the game itself and that is why you will receive an ingame message if or when you ever meet the criteria.

Just in case some one asks what the criteria is.........

"As governorRequirements for relocation: You only have one village and you have at leasttwice as many inhabitants as your current king.As soon as the requirements are met, you will be offered two kingdoms in yourarea, whose kings have more than 50% of your inhabitants and who have beenonline within the last 24 hours.

As kingRequirements for relocation: You only have one village and no active governors inyour kingdom.As soon as the requirements are met, you will be shown two kingdoms in yourarea, whose kings are inactive, yet have active governors. If you confirm theresettlement you will swap places with the inactive king."
